大脑是人体中最复杂的部分,也是宇宙中已知的最为复杂的组织结构。大脑是人体的神经中枢,虽然只有1.5公斤重、但却由140亿个神经细胞组成,人体的一切生理活动都是由大脑支配和指挥的。大脑的复杂性,还在于神经细胞在形状和功能上的多样性,以及神经细胞结构和分子组成上的千差万别。关于大脑功能的研究,已经成为现代科学最深奥的课题,也是最难攻克的科学堡垒。为了探索人脑奥秘,攻克各种疾病,开发人工智能技术,欧美亚等大洲的国家纷纷制定了脑科学研究的长远计划,并宣布21世纪是“脑科学时代”。目前,很多国家在脑科学研究方面取得了可喜的成果,有许多成果还十分有趣。
The brain is the most complex part of the human body and the most complex organizational structure known in the universe. The brain is the body’s nerve center, although only 1.5 kg weight, but by the 14 billion nerve cells, all the body’s physiological activity is dominated and directed by the brain. The complexity of the brain, but also in the shape and function of nerve cells in the diversity, as well as nerve cell structure and molecular composition vary widely. Research on the function of the brain has become the most profound subject in modern science and one of the hardest scientific cornerstones to overcome. In order to explore the mysteries of the human brain, overcome various diseases and develop artificial intelligence technologies, the countries on the continents of Europe, the United States and Asia have formulated long-term plans for brain science research and announced that the 21st century will be the “brain science era.” At present, many countries have made gratifying achievements in brain science research, and many of the results are still very interesting.
